I hate to be the bearer of bad news, just because he takes off his diaper and sticks his hands down his diaper IN NO way means he is ready. He has to have all this in place before he is truly ready
1) be able to understand the urge BEFORE he goes
2) be able to hold it until he can get to the potty
3) be able to pull pants up and down well
4) wake up dry on most naps and most mornings
When those things are in place, he is ready. He is two!
That doesn't mean he is ready to start just getting the experience but you will end up very frustrated if you try and force anything.
DO NOT put him in underwear, I hear that a lot on here and to be honest it will just add to frustration and money in the garbage from seriously soiled underwear. Until he is done don't go with underwear. You can get pullups at Sams or Cosco in bulk very inexpensively.
I successfully potty trained two children (both at three) in a matter of weeks when they were ready, not when I was and doing it with pullups until it was done. It took the stress factor out of it, I wasn't cleaning up pee or poop off the floor, it was very calm, relaxed and at their pace.
Both did it 100% day and night, solely in underwear when we were done and it took two weeks for my son, two and a half weeks for my daughter (who by the way potty trained too early and regressed).
Do not bribe him, reward when he does go. When you finally decide you are ready you need to plan on being home, set a timer and every hour set him on the potty. NEVER ask a child if they have to go, it will be 98% of the time the answer NO! They get distracted and don't want to stop playing. Just pick him up and ask him very nicely "let's go try, if you don't go that is totally fine", see if he can. When he does make a HUGE deal out of it, charts, a few m&ms whatever he responds to. Get a fun potty seat and bypass the potty chair as that will help not have any big potty issues later and less messy.
Be prepared to do the work. Don't get frustrated and keep it very light and at his pace. His internal body has to be just as ready as his brain to do this. If his bladder isn't ready no amount of underwear is going to help. Pushing it too early because you are fed up will only cause regression or make it a power struggle.
He is young, yes some moms do it super early, however that is the exception and it is much better in my opinion to do it once and for all then a ongoing process.
Give him time.
